* **Company Headquarters Location:** Denmark
### Acknowledgments
**Vera Mens** of **Claroty Team82** reported these vulnerabilities to **CISA**.
### Recommended Practices
**CISA** recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Key recommendations include:
* Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
* Locate control system networks and remote devices behind firewalls and isolating them from business networks.
* When remote access is required, use more secure methods, such as Virtual Private Networks (**VPNs**), recognizing **VPNs** may have vulnerabilities and should be updated to the most current version available. Also recognize **VPN** is only as secure as the connected devices.
**CISA** reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
**CISA** also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several **CISA** products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
**CISA** encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to **CISA** for tracking and correlation against other incidents.
**CISA** also recommends users take the following measures to protect themselves from social engineering attacks:
* Do not click web links or open attachments in unsolicited email messages.
* Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
* Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
No known public exploitation specifically targeting these vulnerabilities has been reported to **CISA** at this time.
